R., OF CHICAGO, ILLINOIS,

OF CHICAGO, ILLI- DUMP-'CAFL SPECIFICATION forming part of Letters Patent No. 764,355, dated July 5, 1904.

[Implication filed July 11, 1903.

To all whoiit t 'n1/(ty concern.'

Be it known that we, HARRY StriLLsoNl-IART and O'ino l/V. MuissNEu, citizens oi' the United States, residing at Chicago, in the county of Cook and State oi Illinois, have invented certain new and useful Improvements in Dump- Cars, oi' which the following is a specification.

cars-all of which will more fully hereinafter appear.

The principal object of the invention is to provide a simple, economical, and eilcient convertible dump-car.

Further objects oiy the invention will appear from an examination oi' the drawings and the following' description and claims.

The invention consists principally in a convei'tible d ump-car in which there are combined a supporting-framework provided with downwardly and outwardly extending side discharging-aprons, side boards pivotall y secured longitudinal center, and swinging upper portions fulcrumed in the traine of the cai' and adapted to be moved to a position where they inclineupwardly and outwardly to form the upper inclined portions of the V-shaped hoppei' and to be folded upwardly and inwardly into a second position to form, in connection struction hereinafter described and claimed.

In the accompanying drawings, Figure l is Serial No. 165.199. (No model.)

it appears when constructed in accordance with these improvements; Fig'. 4, a cross-sectional view ot the cai', showingI the lvarious 50 a cross-sectional elevation showing' the parts S 5 arranged to form a Hat-bottom gondola car.

In illustrating and describing these iinprovements we have only-illustrated and will describe that which we consider to be new,

taken in connection with so much as is old as GO will properly disclose the invention to others and enable those skilled in the ai't to practice the same, leaving' out of consideration otliei' and well-known .elements which, it set forth herein, would only tend to confusion, pro-65 lixity, and ambiguity.

In constructing a cai' in accordance with these improvements we provide a supporting'- Iframework which has a discherging-apron (t inclined downwardly and oiitwardly at each 70 side from end to end oit' the car. This supporting-fi'ainework has also a V-shaped'hopper portionformed of one'iixed section and a swinging section c, arranged lengthwise olf n 1 l` the car and with its apex at er near the lon'- 75 g'itudinal center and between the` car-trucks only, as shown particulai'lyin Fig'. 2. "This supporting-framework is iiii'ther provided with a pair ol longitudinal sills (l, one et' which is arranged intermediate the V-shaped SO hopper and each discharging'-apron, to the frame portions of which they are connected by means of brace-rods c, which' lead therefrom to the diseliarging-api'ons. A second set of bi'acc-rodsf leads from said interme- S5 diate sills to the framework o'l.E the V-shaped hopper portion. A plurality oliupwardlyextending' side posts g is provided, attached at their loweredg'es, by means el gusset-plates p /t and brace-rods '/I, to the frame ot' the dis-1h90 charging-aimons and connected together in'an a side elevation oi' one end of a car as it appears when constructed in accordance with these improvements; Fig. 2, a perspective detail of the angular locking-bar hereinafter` described; Fig. 3, an end view of the caras efficient manner at or near their upper edges by means of channel-beamsy', which extend i the entire length ol' the car. To these upper channel-beams are pivotally connected side boards It', formed of a plurality of swinging sections, having their lower free edges arranged to be brought into meeting contact with the outer lateral edges of the discharging-aprons and form in connection therewith a side-dumping car and in connection with the V-shaped hopper a combined side and center dump car.

To operate the swinging section which forms a discharging-door for the V-shaped hopper, the usual rock-shaft Zand chain mechanism mare provided and connected with such swinging section in the usual and ordinary manner. To lock the swinging side boards, however, an improved mechanism must be provided, and for this purpose we provide locking angle-bars at, one of which is arranged at or near each side of-the car and by means of swinging L-bars o are pivotally secured to the supporting-framework of the car. Each of these L-bars-and there are several at each side of the car-have one portion forming a curved projecting linger p, which while the parts are being swung to their locking posi- A tion, as hereinafter described, will iirst contact the lower edges of the swinging side boards before they are quite closed and force them into closed position, when the anglebars, as shown particularly in Figs. 5 and 6, will finally Contact and hold the doors closed in vertical position and at the same time form a seal to prevent discharge of comminuted material. To operate these locking anglebars as desired, a rock-shaft q is rotatably mounted in bearings at or near the upper edge of each side of the car and provided with chain and rod mechanism r, connected with eye-bars s on the angle-bars, so that as such rock-shafts are rotated in one direction the angle-bars, with their closing-fingers, are moved toward locking position, while during the ro- -tation of the rock-shaft in vthe opposite direction they are permitted to drop into the poi sition shown in Fig. Lto allow the side doors to be opened.

To form the convertible means,a pair of upper swinging sections t is provided and arranged so that they may be moved into one position, (see Fig. 5,) where they form the upper inclined portions of the V-shaped hopper, and into a second position, (see Fig. 4,)

where they, form the upper inclined portionsl -of (and in connection with the dischargingaprons) an A-shaped side-dumping bottom. It is desirable to provide means for fulcruming and holding these upper swinging' sections in their diferent positions. In order position to the Lipper edges of the discharging-aprons, which form the fulcrum-blocks for the upper swinging sections when the same are arranged in their A-shaped position. These upper swinging sections extend from end to end of the car, and it is very desirable to provide some means to hold them in their A-shaped position; otherwise a heavy load in the car of coal, sand, rock, or the like might tend to displace them. To provide such means, removable end boards are provided, one at each end of the car, having' outer end stakes y, the lower ends of which are arranged to rest in metal pockets 2. The inner faces of these removable end boards are provided with inwardly-extending cleats 10, arranged in an A- shaped manner, so that they contact the ends of the upper swinging sections and prevent them from being displaced when the car is being loaded or in, fact at, any time until the end boards are removed. It will be understood, of course, that it is necessary to remove theseend boards before the upper swinging sections can be moved from or into their A- shaped position. In Fig. 6 we have shown these upper swinging sections arranged in a third position-viz., a position in which they form the flat bottom of a gondola car, and in order to hold them in such position the upper edges of such swinging sections are provided with angle-blocks ll, adapted to engage with a U-shaped locking-bar 12 at or near cach end of the car. Vhen the parts are in this position, as shown in Fig. 6, the meeting edges of the movable sections are locked in such U-shaped block and held against lateral displacement.

In a car of the class described, the combination of a supporting-framework provided with upwardly-extending side boards formed of swinging sections pivoted at their upper edges, and locking "angle-bars pivotally secured 'to the framework of the car near the sides thereof to engage with the lower free edges of the swinging doors to seal and hold the same in locked position, substantially as described.
